More Than Dispensing: Pharmacists as Immunizers

On average, 5% to 20% of the United States population develops influenza each year according to the US Centers for Disease Control and Prevention (CDC). This leads to more than 200,000 preventable, complication-related hospitalizations.1 An affordable way to prevent diseases such as influenza, commonly known as the “flu,” is to administer vaccinations. Currently, most patients receive their annual flu vaccine from their primary healthcare provider. During the peak months of the flu season, physicians have an added responsibility to administer influenza vaccines, which may become a challenge with conflicting patient and office schedules along with high demand for the vaccine. To close this gap in care is the community pharmacist—a more readily available healthcare provider for patients.

Pharmacists Increasing Vaccination Rates

A small number of pharmacists were first trained to vaccinate in Seattle, Washington in 1994. In 1996, the American Pharmacists Association (APhA), began its national training program for pharmacist immunization certification.2 Now, all 50 states allow pharmacists to become certified immunizers by completing a training program sponsored by APhA.3Figure 1 shows the positive difference in influenza vaccination rates from 1995 and 1999, when more states began to allow pharmacists to vaccinate.

Figure 2 shows the percentage of the US population who were vaccinated in the 2010/2011 flu season, demonstrating that a large amount of the population is not getting vaccinated and, as a result, there is a need to increase vaccination rates.

Pharmacists' Role as Immunizers

Pharmacists can play a role as advocates, partners, and providers of immunization to improve vaccination awareness. In this multifaceted role, pharmacists may help increase public knowledge of vaccines and dispel common myths about them; work with nurses and other healthcare providers
to advocate immunizations; and also administer vaccines to help increase vaccination rates.6

One survey, conducted from 2008 to 2009, included 2167 healthcare workers (HCW) and evaluated the changes in vaccination rates when pharmacist-driven immunization programs were used. Figure 3 shows how pharmacists who administered the vaccine helped increase vaccination rates when
compared to the 2008 national vaccination rate for HCW.7
